IMPROVEMENT IN 1mois-La'rcrar'is.

'The Schedule referrnd to in these Letters Patent and making part of the name.

To all whom it may concern: Y

Be it known that I, F. P. PFLEGHAR, of New Haven,

in the county of N ew Haven, and State of Connecticut, have invented a ne'w Improvement in Knobllatches; and I do hereby declare the following, when `taken in connection with the accompanying drawings,

and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, the stile of the door, with the latch and by which the rose is secured, must 'necessarily be` short, else they would strike the case of the latch.

From this cause, that is,A the necessarily e short screws, the rose upon a door much used soon becomes loosened and the screws displaced.

By my invention these diliiculties are entirely overcome; and

It consists in arranging the follower within the rose and outside the door-stile, so that the knob or spindle will pass through the follower above the lockcase and a lever within the rose, acted upon bythe fbllower, yand attached to the latchbolt,' 4serves to communicate the action of the follower` to the latchbolt.

A is the door-stile g B, the latch-bolt, arranged within `the case, as seen in iig. 4, the tail'G of the bolt extending back toward the rear of the case.

An eye, D, and a slot, E, corresponding thereto, are formed in the case,so that a pin inserted'through the slot into the eye D, and drawn back, will draw in the latch-case.

bolt, as denoted in broken lines, iig. 4, thus dispensing entirely with the follower within 'the case.

E is the rose, within which, as seen in fig. 3, the follower L is placed, a bearing being formed in the rose for thefcllower.

I is a lever, arranged within the rose, as also seen in fig. 3, so that by the turning of the follower in either direction, the said lever will be moved, as denoted in broken lines, iig. 3, and also denoted. in tig. 2.

0n the said lever is a pin, a, which passes through a slot, d, in the door, and so as to enter the eye D of the latch-bolt, the latch-case'liaving been inserted into i the door in the usual manner.

The lever is arranged upon the stile, as seen in tig. 2, the spindle passing through the door at N, above the latch-case, and the screw f, by which the top of the rose is secured tothe door, also passes through, and so as to form a fulcrum for the lever at n and this screw may be of any desirable size and length, less than the thickness of the door, as the latch-oase is entirely below.

" By preference, I make the escutcheon P :a part of the rose,which brings the lower screw s below the Hence, I am enabled to secure the rose in the strongest possible manner, and also vto use a very narrow latch-case, which last avoids cutting the door.

between the rose and the door, to operate on a latch by means of a pin working in a slot ,of the door, the said 'lever being operated through a slot itl the rose instead ofv by means of the follower and knobshank. Such arrangement, therefore, I do not claim.

I claim, as my inventionv v 1. The arrangement of the lever I and follower L, outside the latch-case, and combined with the latch, in the manner described. l

2. The combination of the rose F, lever I, and follower L, when the said rose is constructed so as to enclose the said follower and lever outside the doorstile.

I am aware that the lever has been before arranged I
